Can I delete Arc Browser from my Mac?

Yes, you can delete it

You can delete Arc Browser from your Mac, especially since The Browser Company shifted focus to Dia in 2025. Doing so removes the application but leaves your personal data intact unless you manually delete specific folders.

What you lose and keep when deleting Arc Browser

Specific to Arc Browser

Removing the app leaves your profiles and sidebar configuration untouched in ~/Library/Application Support/Arc, which holds your own data. Arc Sync preserves Spaces and pinned tabs in your account, but history, cookies, and saved passwords remain local. The app’s cache files rebuild automatically, so clearing them only fixes stale content or slow performance. Your local setup persists until you explicitly remove the data folders.

Where your Arc Browser data lives

These folders hold your own Arc Browser data. Deleting the app leaves them in place; removing them is what actually deletes it.

~/Library/Application Support/Arc App data · browser profiles, Spaces, sidebar layout, history and cookies Back up first: your data~/Library/Application Support/Arc/StorableSidebar.json App data · your Spaces, pinned tabs and folders in the sidebar Back up first: your data

Current status: The Browser Company stopped adding new features to Arc in 2025 and moved its focus to its Dia browser; Arc only receives maintenance and security updates.
Account and sync: Arc requires an Arc account; Arc Sync can carry Spaces, pinned tabs and folders to other Macs, but history, cookies and saved passwords stay in the local profile folder.

Steps to take before removing Arc Browser

You should verify that Arc Sync is active to back up your sidebar to the cloud. Export bookmarks and passwords because these items do not sync automatically. Quit the application completely before moving it to the Trash to prevent data corruption. Remember that items in the Trash can be restored until you empty it.
